    <p>Yes, using i.e. Virtualbox to run your VM, you can define "Shared

      accessible from within the VM. (Don't know about sharing from a

          Hi Neil,
          <br>
          I run QGIS on an iMac i3 (12GB RAM) and on a MacBook Pro i7
          (8GB RAM).
          <br>
          Both work fine.
          <br>
          Installation is super easy. Just follow William Kyngesburye's
          <br>
          instructions as Lee has already mentioned.
          <br>
          <br>
          I think, and I am neither a GIS nor a QGIS specialist (just a
          very
          <br>
          limited user), combining QGIS with GRASS gives you the same
          range of
          <br>
          functionality as ArcGIS has.
          <br>
          Again, I am not a hard core GIS person but I used it a bit for
          spatial
          <br>
          modelling of hydrogeological and hydrological projects.
          <br>
          The GRASS installation is very easy on a Mac, too (again,
          follow
          <br>
          William's instructions ... Thanks William!!!)
          <br>
          <br>
          I also had run an ArcView version 9.3 on a virtual computer
          (on the
          <br>
          iMac) using VirtualBox and Windows XP with a memory allocation
          of 4GB.
          <br>
          That also worked fine without any issues. It certainly depends
          also on
          <br>
          what you want to do. I am not sure about ArcInfo and a Dongle
          <br>
          compatibility, referring to Lee's answer.
          <br>
          <br>
          There is only one thing that I don't like that much with QGIS,
          which is
          <br>
          making and editing good looking maps for presentations or
          publication.
          <br>
          It seems a bit clunky to me (e.g. scale issues between QGIS
          desktop and
          <br>
          map composer, rotation of labels (I have managed it but it
          took me
          <br>
          forever to find out how), etc.).
          <br>
          It is absolutely likely that I don't know all the tricks and
          tweaks how
          <br>
          to use it but this process seems to be a bit easier in Arc. I
          usually
          <br>
          export the map and do the fine editing in a graphics software;
          however,
          <br>
          it sometimes becomes a bit cumbersome when there is lots to
          edit that
          <br>
          potentially could be done much easier by editing a layer in
          the GIS.
          <br>
          (to all the others, please comment on that. I want to learn 
          ... )
          <br>
          <br>
          Hope that helps,
          <br>
          <br>
          Cheers,
          <br>
          Harald

              day overview course
              <br>
              at GISRUK 2012 and realised that it really is becoming a
              practical
              <br>
              alternative to Arc.
              <br>
              One of the many attractions of it is the possibility to
              also escape from
              <br>
              windows.
              <br>
              <br>
              So I am looking at buying an Apple Mac and was hoping for
              some advice :
              <br>
              <br>
              a) What are the limits to the resources that QGIS can
              realistically use
              <br>
              (i.e. in the same way that ArcMap is still pretty much
              stuck with single
              <br>
              core 32bit processing so there isn't much point sticking
              16Gig of memory in
              <br>
              a machine running it).
              <br>
              <br>
              b) If I do go with Mac, am I better to install the Mac
              version of QGIS or
              <br>
              run Linux also.
              <br>
            </blockquote>
            Installation on Linux is *probably* more straightforward.
            For
            <br>
            installing on Mac, one of my students found
            <br>
            <a class="moz-txt-link-freetext" href="http://www.kyngchaos.com/software/qgis">http://www.kyngchaos.com/software/qgis</a> helpful. The only
            reason I can
            <br>
            think of to run QGIS in Linux instead of Mac is if you
            expect to be
            <br>
            regularly working with other Linux software and don't want
            to keep
            <br>
            switching OSes. I would definitely try it on Mac first if
            that's your
            <br>
            preferred OS.

              resources between two machines).
              <br>
            </blockquote>
            ArcGIS runs fine in a VM. You may run into problems if you
            need to run
            <br>
            a version like ArcInfo that requires a hardware dongle for
            <br>
            authentication. I've only been using a version requiring an
            <br>
            alphanumeric key. A coworker who tried to get ArcInfo
            running on a
            <br>
            Windows XP guest on a Fedora host eventually just gave up.
            <br>
            <br>
            You do have to divide your resources between machines, but
            given how
            <br>
            much RAM most machines come with these days, that's usually
            not much
            <br>
            of a problem (until you start talking about running multiple
            guest
            <br>
            OSes simultaneously). If you still have access to WinXP, I
            would
            <br>
            consider running Arc on that because of the minimal resource
            <br>
            requirements. 1-2 GB of RAM is all you will need (and you
            could get by
            <br>
            on<1 GB of RAM) assuming the guest OS isn't running
            anything other
            <br>
            than Arc. Make sure to dedicate some of your video memory to
            the guest
            <br>
            OS.

            things that are typically slow elsewhere, e.g. multiple
            layers with
            <br>
            many (1000s) features, are still slow, but everything else

          To update this post,

          <br>
          I have compared the project file code for both the layer that
          works and
          <br>
          the layer that doesn't and I have found differences in the
          <br>
          customproperties section. This section does not exist in the
          layer that
          <br>
          works - it only exists for the layer that I copied the style
          for.
          <br>
          Removing it makes the layer show on the map.

          Subject: [Qgis-user] Query Layer / Rule Based Rendering
          Problem
          <br>
          <br>
          I have created a query in the DB Manager SQL Window (data is
          in a
          <br>
          PostGIS database). The query is then added to the map as a
          layer.
          <br>
          <br>
          I copy the style from another layer (rule based style), paste
          it to my
          <br>
          query layer and the polygons disappear from the map and QGIS
          gives a
          <br>
          nextFeature() without select() error. This also happens if I
          apply a qml
          <br>
          style file to the layer.
          <br>
          <br>
          If I change the styles back to Single Symbol they do not come
          back. I
          <br>
          can see the records in the Attribute table, and I can select
          them and
          <br>
          zoom to them on the map, I just cannot see them.
          <br>
          <br>
          I have to re-add the query layer using the DB Manager SQL
          window again.
          <br>
          <br>
          It only seems to be the polygon layers that cause problems at
          the
          <br>
          moment.
          <br>
          <br>
          Does anyone know the cause of this?

          Subject: [Qgis-user] Query Layer / Rule Based Rendering
          Problem
          <br>
          <br>
          I have created a query in the DB Manager SQL Window (data is
          in a
          <br>
          PostGIS database). The query is then added to the map as a
          layer.
          <br>
          <br>
          I copy the style from another layer (rule based style), paste
          it to my
          <br>
          query layer and the polygons disappear from the map and QGIS
          gives a
          <br>
          nextFeature() without select() error. This also happens if I
          apply a qml
          <br>
          style file to the layer.
          <br>
          <br>
          If I change the styles back to Single Symbol they do not come
          back. I
          <br>
          can see the records in the Attribute table, and I can select
          them and
          <br>
          zoom to them on the map, I just cannot see them.
          <br>
          <br>
          I have to re-add the query layer using the DB Manager SQL
          window again.
          <br>
          <br>
          It only seems to be the polygon layers that cause problems at
          the
          <br>
          moment.
          <br>
          <br>
          Does anyone know the cause of this?
